With the development of the third wave of specialty coffee, Pour over(V60) coffee has become popular among enthusiasts. Many enthusiasts like to brew Pour over(V60) coffee at home. Is it difficult to brew Pour over(V60) coffee? In fact, it is not difficult to learn to brew Pour over(V60) coffee.
When FrontStreet Coffee's baristas produce Pour over(V60) coffee, they will choose 15 grams of coffee beans and a powder-to-water ratio of 1:15, which means they will inject 225 grams of water at the end. Choose hario v60 filter cup or kono filter cup according to different coffee beans. Wet the filter paper with a small amount of water before each brew to make the filter paper and filter cup fit better.
The main factors that affect the taste of Pour over(V60) coffee are the following: grinding degree, water temperature, powder-to-water ratio, extraction time, etc. Among them, the finer the grinding degree, the richer the coffee taste, the coarser the grinding degree, the lighter the coffee taste; the higher the water temperature, the stronger the coffee taste, the lower the water temperature, the lighter the coffee taste; the larger the powder to water ratio, the lighter the coffee taste, the lower the powder to water ratio, the richer the coffee taste; the same goes for the extraction time, the longer the time, the thicker the coffee taste, the shorter the time, the lighter the coffee taste.
Why is brewing time so important?
The coffee brewing process is an extraction process. Water serves as a solvent to dissolve coffee flavor substances from the coffee powder. All influencing factors directly or indirectly affect the extraction efficiency of coffee. Extraction time or brewing time refers to the contact time between coffee powder and water. The longer the contact time between powder and water, the more time the water flow has to dissolve and extract the substances in the coffee powder, and the taste will of course be stronger, and vice versa.
What affects the brewing time of Pour over(V60) coffee?
The structure of the filter cup
The structure of the filter cup is the first factor that affects the brewing time of Pour over(V60) coffee. Different filter cups will have different speeds in filtering coffee. For example, there are two filter cups produced by FrontStreet Coffee: v60 filter cup and kono filter cup. The v60 filter cup is designed with large-diameter filter holes and spiral-shaped exhaust ribs. This design makes the v60 filter cup filter very quickly. The overall design is more inclined to drip extraction, which increases the layering of coffee.
The design features of the kono filter cup are straight and shorter ribs and smaller filter holes, which make the filtration speed of the kono filter cup slower. The overall brewing time will be longer than that of the v60 filter cup. Therefore, when brewing with the kono filter cup, the gouache will be soaked longer than the v60 filter cup, bringing a fuller taste.
Amount of powder
In addition to the filter cup, the amount of coffee powder can also affect the flow rate of coffee, which indirectly affects the brewing time of Pour over(V60) coffee. For example, the product produced by FrontStreet Coffee store uses 15 grams of coffee powder. The more coffee powder, firstly, more water injection time is required, and secondly, the thicker the powder bed, the slower the flow rate.
Imagine that with the same water injection speed of 10 grams per second and a powder-to-water ratio of 1:15, 15 grams of coffee powder needs to be injected with 225 grams of water, and the water injection time takes 22.5 seconds; while 20 grams of coffee powder needs to be injected with 300 grams of water, and the water injection time takes 30 seconds.
Water injection speed
The water injection speed is easier to understand. The faster the water injection speed, the shorter the brewing time and the weaker coffee taste. On the contrary, the slower the water injection speed, the longer the brewing time and the more obvious the coffee taste.
Grinding degree
The final degree of grinding is also a factor that affects the brewing time of Pour over(V60) coffee. I wonder if you have had such an experience. After pouring water into the Pour over(V60) coffee, the entire powder bed becomes a muddy mess, and the coffee liquid cannot be filtered, as if it is blocked. This is the most extreme example of the thickness affecting the brewing time - the coffee powder is too fine and the flow rate is too slow.
The influence of coffee powder thickness on brewing time can be understood as the gap between the particles. The finer the coffee powder, the shorter the gaps between the coffee particles, the harder it is for the water to flow through these gaps, and the flow rate slows down; conversely, the thicker the coffee powder, the larger the gaps between the coffee particles, the easier it is for the water to flow through these gaps, and the flow rate speeds up.
How long should hand brewing coffee take?
After the above series of introductions, we now know that the brewing time of coffee is actually affected by many factors. Just like the final taste of Pour over(V60) coffee is affected by many factors, this is the result of a combination of factors. There is no fixed standard for any factor. The combination of these factors can make different brewing plans, such as fine grinding and fast brewing, coarse grinding and slow brewing, etc.
The same is true for brewing time, but for novices who have not yet understood the impact of various factors on brewing, FrontStreet Coffee's brewing plan is very suitable for you. FrontStreet Coffee's baristas often share with customers: FrontStreet Coffee's brewing method is the most basic, most basic, and very easy to imitate the brewing plan. The purpose is to allow everyone to brew the taste you drink in a cafe at home.
The brewing plan of FrontStreet Coffee is based on the practice of many baristas over the years. It chooses a v60 filter cup, 15 grams of coffee powder, a powder-to-water ratio of 1:15, a medium-to-fine grinding degree, a water temperature of 90 degrees Celsius, and three-stage injection. The final brewing time is 2 minutes. About 2 minutes is when the coffee liquid is completely filtered. Remove the filter cup and end the brewing.
In the first stage, 30 grams of water is injected for steaming, and the steaming time is 30 seconds; in the next one minute and 15 seconds, all the remaining 185 water is injected, so it takes about 2 minutes to 2 minutes and 10 seconds to complete the entire brewing process.
If, during this process, water injection cannot be completed in one go, it can be achieved through segmented water injection. In the second stage, 125 grams of water is injected. After an interval of 10 seconds, 225 grams of water is injected. The total extraction time is about 2 minutes.
This brewing time is based on the grinding degree and powder-to-water ratio. It is less than2Minutes, the coffee taste is not enough, more than2Too many minutes will result in a bitter taste.
